Jesverty's SPS series is a high-efficiency, compact, lightweight, high-performance Switching mode DC regulated power supply. It can be used as a constant-voltage(C.V.) power supply and constant-current(C.C.) power supply. Also, convenient functions like a USB type-A charging port, and a high-precision 4-digit LED display showing V／A／W are standard in this power supply. It's perfect for school education, laboratory experiments, industrial testing, and electrical DIY projects at home.

1️⃣【4-Digit Display & Power Calculation】: Jesverty bench power supply features a big bright 4-digit LED display that shows measured values of V／A／W that the unit outputs in real-time. The display resolution is up to 0.01V, 0.001A, and 0.1W. 
2️⃣【Auto C.V. and C.C. Mode】: Jesverty variable power supply can be used as a constant-voltage*(C.V.) power supply and constant-current*(C.C.) power supply even when the load is changed. It switches automatically between CV mode and CC mode according to the changes in the load. 
※Note: The V and A settings you set are the crossover point at which the mode switches. 
3️⃣【Compact Body & Lightweight】: Jesverty DC power supply variable measures only 7.1(D)x3.35(W)x6.1(H)inches and weight of approx. 1.2kg. It saves space on your workbench and can be moved around without any frustration. 
4️⃣【Reliability and Safety】: Jesverty benchtop power supply is built with high-quality materials and reliable circuit designs that include multiple protection functions, such as short-circuit protection, over-load protection, grounding terminal, temperature-regulated fan, etc. to ensure performance and extend the lifespan.
